Yes, I see how to setup payment terms and am good with that.

I also see how to setup"Payment Terms" for each customer individually.  This is close to what I want to do but it requires me to remember to set "Payment Terms" when creating each customer.

I had thought there would be a way to set the "Payment Terms" on an invoice template.  I have it set so that the Terms field is displayed but it is blank on new invoices unless I i) previously set the "Payment Terms" when creating the customer the invoice is being prepared for or ii) specify the terms when creating the invoice.  I typically use the same terms for all invoices prepared using that template.

I guess one workaround would be to unselect TERMS on the invoice template and then add a text box that says "TERMS: Due on receipt" so those terms appear on all invoices created using that template.  

The reason I asked is because I created some new customers and produced an invoice for each customer but forgot to specify terms.  Consequently,  the invoice just shows  the title TERMS but the field is blank.
